Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Lift the vehicle using a hydraulic jack and secure it with jack stands.

2. Remove Wheels

Use a lug wrench to loosen and remove the lug nuts.
Take off the wheels to access the suspension components.

3. Inspect and Replace Components

Control Arm Bushings:
- Remove the bolts securing the control arms using a socket set.
- Replace worn bushings with new ones, ensuring they are properly aligned.
Sway Bar Links:
- Remove the sway bar link bolts using a wrench and socket.
- Install the new sway bar links and torque to manufacturer specifications (typically around 30-40 Nm).
Struts/Shocks:
- Remove the strut assembly by unbolting the top strut mount and lower bolts.
- Replace struts/shocks if they show signs of leakage or damage.
- Reinstall the new struts and torque the bolts to specifications (usually 60-80 Nm for lower bolts).

4. Reassemble Vehicle

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle to the ground and torque the lug nuts to the specified value (typically 100-120 Nm).
Conduct a visual inspection to ensure all components are secured.
